Koko, my serious and plain childhood friend. She came to my house because she wanted me to teach her how to study. When Koko is relaxing, she doesn't mind scratching her ass in front of me at all! Koko, who loves erotic novels, found an erotic comic hidden under her pillow and said, 'I've never seen the real thing, so show me!' Her sexual curiosity explodes! Is she too sensitive to squirt on her first time!? We practice erotic acts by watching and mimicking each other...!
